The record set 0 of the counter function, frequency meas-
urement and pulse width modulation has the same struc-
ture. There are differences in the structure of record set 1.
The record set 1 contains the 4byte of the record set 0 and addition-
ally 12byte module specific diagnostic data. The diagnostic bytes
have the following assignment:
